Happy 83rd birthday to Playboy magazine founder Hugh Hefner... and an excuse for a few pictures of Hef\'s past and current hot girlfriends.
The guy is well past retirement age, and still running the magazine. Plus, despite breakups with former "Girls Next Door" Holly Madison, Kendra Wilkinson, and Bridget Marquardt...
Hef has quickly rebounded to three new hotties, Crystal Harris, Karissa Shannon, and Kristina Shannon.
And YES, the Shannon girls are TWINS.
God bless ya Hef. Here\'s to many more years of living the dream.
